SOLOMON EUGENE HALL, OF HONEOYE FALLS, NEIV YORK, ASSIGNOR OF ONE-HALF TO GEORGE HILL, OF SAME PLACE.

WRENCH.

SPECIFICATION forming part of Letters raient No. 466,564, dated January 5, 1892. Application tiled October 14, 1891. Serial No. 408,656. (No model.) i

To a/ZZ whom t may concern.-

Be it known that I, SOLOMON EUGENE HALL, of Honeoye Falls, in the county of Monroe', in the State of New York, have invented new and useful Improvements in Wrenches, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

l My invention relates to improvements in wrenches, and has for its object the production of a simple and effective device which is strong, durable, easily adjusted, and very efiicient in use. l,

To this end the invention consists, essentially, in a handle having an annular guidegroove, a disk provided with a shoulder adapted to engage said groove, a guideway extending transversely of the disk,jaws movable in said guideway and provided with a recess in their sides for engaging a projecting shoulder of the way, an adjusting-screw for moving the jaws toward and away from each other, and a dog for securelylocking said disk and handle together.

The invention furthermore consists in a` pair of dogs having a portion of their face ratchet-shaped, a sliding block orcam for engagin g the dogs and throwing them alternately into and out of operation, ashoulder provided upon one or both of said dogs, whereby it may be partially revolved in order that the dog may engage the disk positively when the handle is rocked in either direction; and it still furthermore consists in the detail construction and arrangement of the parts, all as hereinafter more particularly described, and pointed out in the claims.

In describing this invention reference is had to the accompanying drawings, forming nal vertical sectional view of the parts as illustrated in Fig. l. Y wrench as illustrated in Fig. l, the handle being removed for the purpose of illustrating the underlying parts. Fig. t is a transverse vertical sectional view taken on line y y, Fig.

Fig. 3 is a rear view of the `l. Fig. 5 is a rear face view of the movable block or cam for forcing the ratchet-dogs into and out of operative position. Figs. 6 and -7 are respectively isometric perspectives of the ring on the handle and a hub removably secre'd thereto. Fig. 8 is an isometric perspective of the Wrenchjaw; and Fig. 9, a detached View of the ratchet-dogs in position for firmly securing the revoluble disk or rod upon which the jaws are mounted to the hanformed with a ring b, the outer edge of whichv encircles the ring d, and with a rearwardlyextending end b', which is formed with a recess or groove b2, having shoulders b3, adapted f to bear against opposite sides of the handle A. A screw or clamp B4 securely draws together the handle A and the projection b of the plate B, and screws b4, movable in the peripheral edge of the hub b, secure together the rings b and a. These rings o and b are so arranged in relation to each other that, as best seen at Fig. 2, the annular guide-groove C intervenes between the adjacent faces of said parts.

D represents a disk revoluble within the groove C and provided with an outwardly-extending disk-shaped projection D', which is formed with a guideway d, having the projecting shoulder d. I

For the purpose of cheapening the production the disk D and its disk-shapedprojection D are formed separate one from the other and are firmly secured together by screws D2.

Movable within the groove d'andprojecting outwardly therefrom are the Wrench-jaws E, which are formed in their side faces with recesses e, adapted to receive the projecting shoulder d and retain said jaw firmly in position. .y Y

The jaws E are adjustable toward and away from each other by a suitable adjuster F,

IOO

here illustrated as a screw having its opposite extremities formedwith oppositely-turned threads and its central portion provided with a hand engaging wheel f, which extends through the disk D in order that it may be readily engaged from the rear of the wrench through the opening in the ring a. The jaws can thus be easily adjusted from the rear of Wrench, and when in position are iirm and do not have the slightest tendency to yield or spring.

Formed in the disk D, and preferably in its edge, are notches g, with which are engaged one or more ratchet-dogs G, which, as best seen at Figs. 2 and 3, are mounted in recesses g in the projections h of the ring B. The rcarextremity of the dog gis of less diameter than the forward engaging portion, and encircling the same, with one end bearing against a shoulder g2 of the recess, is a spring g3, which automatically forces said dog outward into cnn; gagement with the notches g in the disk. The

- rearward extremity g of the dog G extends outwardly beyond the rear face b5 of the project-ion band is provided with a shoulder g4, adapted to be engaged by a cam H 'for forcing the dog out of operative engagement with the disk. As preferably constructed, there are two of. these dogs side by side, and the cam II is provided at its opposite extremities with ways 7L for permitting the opposite calnfaces h2 to slide beneath the respective projecting ends g when the central portion 71,3 of the sliding block carrying said gam-faces is forced in either direction.

The ratchet-dogs G are provided with shoul ders g5, which may be engaged and the dogs rocked a quarter-way around for presenting square shoulders to the like square shoulders formed at the front and rear of each recess in the disk D, and thus firmly locking the same to the handle irrespective of the direction in which said handle is moved.

It will thus be seen that by manipulating the block Il the wrench may be used as a ratchet-wrench andthe handle moved in either direction and that by slightly turning the shoulders g5 the wrench may then be moved as an ordinary one and the handle moved in either direction.

The operation of my invention will be readily perceived from the foregoing description and upon reference to the drawings, and it is evident that the respective parts are cheaply and economically produced, readily assembled, and are eihcient in operation.

The detail construction and arrangement of the parts of my wrench may be somewhat varied from that shown and described. I-Ience I do not limit myself to the precise form and construction.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a wrench, the combination of a handle having an annular gnideway, a disk revoluble within said guide, adjustable jaws on said disk, and a ratchetdog secured to said handle for engaging notches in said disk, snbstantially as and for the purpose specified.

ln awrench, the combination of a handle having a hub at one extremity, an annular guide-groove in saidhub between the top and bottom faces thereof, a disk mounted in the hub and provided with a flange revoluble within said annular groove, adjustable jaws on said disk, and a ratehet-dog secured to said handle for engaging notches in said disk, substantially as and for the purpose described.

3. In a wrench, the combination of a handle hav-in g an annular guide-groove, adisk revoluble within said guide, a guideway extend ing transversely of the disk and formed with a projecting shoulder, jaws mounted in said guideway and formed with recesses in their sides for receiving said shoulder, a screw for adjusting said jaws toward and away from each other, and a dog for-locking said disk to the handle, substantially as and for the purpose set forth.

4. In a wrench, the combination of a handle having an annular guide-groove, a disk revoluble within said guide, a guideway extending transversely of the disk and formed with a projecting shoulder, jaws mounted in said guideway and formed with recesses in their sides for receiving said shoulder, a screw for adjusting said jaws toward and away from each other, a dog for locking said disk to the handle, and a movable cam or shoulder for disengaging the dog from said disk, snbstantially as described.`

6. In combination, a handle, a disk rcvoluble within one extremity of said handle, a pair of dogs movably mounted on said disk, notches in said disk provided with a forward and backward engaging-shoulder, a springactuated ratchet-dog adapted to engage the notches in the disk, and a shoulder on said dog, whereby the same is engaged and partially rotated for securely locking the disk and handle together when the handle is rotated in either direction,substantially as described.

7. In combination, a handle, a disk revoluble within one extremity of said handle, a pair of ratchet-dogs adapted to engage the notches in the disk, a double cam for alter nately engaging said dogs, and a shoulder on one or both of said dogs, whereby the same may be engaged and partially rotated for securely locking the disk and handle-together when the handle is rotated in either direction, substantially as set forth. J

8. In combination,a hub having a circular recess, a disk revoluble within said recess, a handle having a ring encircling said disk, clamps for securing the formerv hub and the handle-ring togethe1,'a guideway formed in the disk, jaws mounted in the guideway, and
